Product:
Thes formula of these makes this concealer blend into the skin seamlessly! The are semi-opaque products that can be built up for more coverage but because it has a natural translucently to the product once dried down it can't get the full coverage needed to cover out stronger skin
discolouration like my dark blue circles.

That said I've also seen a lot of people use this as an undereye area brightener and these look wonderful in that application as well.

My only complaint is the colour range. Unlike the MUFE Full Coverage Concealer which has 12 concealer (aka skin tone) shades. This range has only 5 concealer skin tones and 5 peach corrector tones to work with. Now this might be a bonus for makeup artists, but for the average consumer you might need upwards of 3 shades to work with your skin tone. In my case the shade Y23 is too dark so I would have to lighten it with either R20 or Y21(which is lighter than R20) to get a proper concealer match and a corrector to cancel out my blue circles with the shade R22.

I did find these creased in my lower eyelid fold but once you tap it out it's ok throughout the day.

Colour:
R20 is a pale peach nude concealer with a satin/matte finish. (This shade is too pale to be a corrector in my books)
R22 is a light peach nude corrector with a satin/matte finish.
Y23 is a yellow ivory nude concealer with a satin/matte finish.

Wear:It wears close to 14 hours on bare skin but you can make it last longer with setting it with a powder or a primer underneath.Packaging: Simple squeeze tube packaging with a rubber nozzle tip.

Verdict
I do like this formula a lot and if you have moderate to medium skin tone discolouration these are lovely to work with for the truly natural finish on the skin.

But if you like me with more prominent discolouration you are not going to get the coverage you need from these even with layering.
